Sold Category 5 Andrew Head + Travel Case


Platinum Supporting Member
This 2 channel, 50W head, provides the ultimate in flexibility. Channel 1 is inspired by a 1961 brown Deluxe and Channel 2 gets you the blackface sound (Remembering Stevie is how Cat 5 describes it). Per Cat 5 this channel is voiced like a blackface amp but with a tighter bottom, smoother treble, more pronounced upper mids, awesome overdrive, and tweek-like response. Plus you get channel mixing and voltage control so you can play at bedroom levels. A full description from the Cat 5 website is at the bottom of this post. You can go to the Cat 5 website to hear sound clips.

This head sells new for $2795. Your cost $SOLD with travel case and I will pay for UPS shipping to the lower 48 states. Payment via PayPal. No trade offers please.

Let me know if you are interested. Thanks!


Andrew's power platform can run a pair Tung-Sol 5881s, which we find to have a rich overdrive, perfect for blues and rock music. It is also possible to run 6L6 tubes for more bottom end, clean headroom and chime, for country and southern rock. Our unique new bias circuit allows Andrew to run these two power tube configurations without re-biasing for those who have an affinity for different tubes. We also bumped the plate voltage to extract more clean headroom from the power amp for players who need more stage volume. Conservatively rated at 50 Watts, Andrew easily keeps up with our excellent 1965 Twin Reverb® sample, which puts out 85 Watts from a quad of 6L6GCs. Andrew actually cuts through better than the Twin. Yeah. We're shaking our heads too.

Like Ivan, Andrew has must-have features including global, tube-driven, spring reverb; a variable recording line out; and an on-board Variac circuit. Guitarists looking for exquisite tone for midsize to large venues should find everything they need in this amplifier named Andrew.

Channel One - That Jimi Thing
The inspiration for channel one was a pristine 1961 brown Deluxe®, which is the wildest sounding amplifier Leo ever made. That little amp's attitude problem caused us to recall some of Jimi's crazier days with his vintage Marshalls®, and we set out to capture some of those killer tones in Andrew's first channel.

Channel one utilizes two cascaded gain stages with a simple low insertion loss tone stack between them. With a slight bump in the mids and plenty of gain on tap, this channel wails with the best tones of the late 60s through the early 80s. Channel one is the perfect preamp to mate with Andrew's custom power amp and combination of the two produces great tone with almost infinite singing harmonic sustain.

Channel Two - Remembering Stevie
Many blues greats prefer black face Fender® amps for their EQ and response, but are forced to use pedals to drive them into creamy overdrive. We designed channel two to capture the magic of the best of Leo's designs from the 60s, but do so in such as way as to cure all of the common ills--no Tube Screamer needed.

Andrew's second channel is voiced something like a black face amp, but with a tighter bottom, smoother treble, more pronounced upper mids, awesome overdrive, and tweed-like response. Its tone can vary from warm and woody to punchy and reedy. It has enough overdrive available to replace your pedals with the volume control on your guitar. This makes it ideal for blues players and rockers alike.

Channel two uses three cascaded gain stages from a unique combination of preamp tubes to shape its tone. Its extra hot preamp bias produces a very warm and round tone with absolutely endless sustain reminiscent of early Carlos Santana. Like channel one, this channel takes advantage of the tendency of the power amp to sing with rich harmonics.

Voltage Control
The Voltage control is something like a built-in Variac. It allows you to apply as little or as much voltage to the plates of Andrew's preamp and power tubes as you like. At one extreme, Andrew can be turned down to a total output of 5 Watts for bedroom practice. Turning the control all the way up sets Andrew to run at its maximum of 40 Watts RMS. The Voltage control is not a master volume, but it is what a master volume should be: consistent sound, variable loudness.

This control also slightly changes the tone of the amp and does so in very usable and musical ways. Turn the control down for a "browner" sound or turn it up for more clean headroom. Your tone stays fundamentally the same at every setting, but subtle differences in the "brown" quality can be attained using this control.

Finally, the Voltage control has the potential to greatly extend the lives of your preamp and power tubes. Most players set this control somewhere between 50% and 75%, which applies less voltage and less current draw (cooler bias) than if the amp were permanently set to maximum voltage and bias as it would be if the Voltage control were not included. Used in this manner, your tubes can last 100% longer or more.

Active Channel Mixing
Traditional design philosophies hold that it is less expensive--therefore more desirable--to mix the channels in a two channel amplifier using resistive mixing methods. We don't let cost dictate design at Category 5. We know active mixing is a far better approach even if it does require an extra preamp tube. Andrew's two discrete channels are actually mixed together inside a dedicated 12AX7 preamp tube before being injected into the reverb driver circuit and continuing on to the phase inverter. In this scenario, the two channels are kept completely discrete and isolated from each other, which keeps the tone of each channel pure.

Hand-selected premium components are used in each Andrew amplifier. We auditioned many different types and brands of resistors, capacitors, and other electronic parts to find exactly the right mix of components to make Andrew sound its best. Best of breed parts such as Austin Speaker Works speakers, Schumacher boutique transformers, Mallory and styroflex capacitors, Tung-Sol power tubes, and Analysis Plus cables punctuate this rigorous selection process.

Like all Category 5 amplifiers, we build Andrew with overbuilt structural components and manufacturing methods such as a laser punched 2mm thick aluminum chassis, stainless steel and brass hardware, and a voidless 11 ply baltic birch cabinet that is finger jointed and heavily braced for a lifetime of reliability. The face plate is laser engraved stainless or anodized aluminum, which while very expensive, will never fade, crack, or have its lettering scratch off. Andrew will probably outlive you.
